Abstract

The invention relates to a one-bath processing method for pure-cotton knitted fabric scouring and bleaching and pigment dyeing, belonging to the technical field of textile dyeing and finishing. The process adopted in the invention comprises the following steps: (1) carrying out scouring and bleaching treatment on pure-cotton knitted fabric, wherein waste liquid discharge is not needed after the treatment is completed; (2) after the scouring and bleaching treatment is completed, adjusting the treating fluid to a certain condition, and then adding catalase, so that residual hydrogen peroxide is sufficiently decomposed; and (3) preparing a pigment dyeing solution by utilizing the residual fluid and dyeing the pure-cotton knitted fabric, adding a binding agent to the residual fluid after the dyeing is completed for fixation, and finally taking out the knitted fabric and carrying out dehydration, drying and curing treatment. According to the invention, two processes, namely pure-cotton knitted fabric scouring and bleaching and pigment dyeing, are combined and carried out in a same treatment bath, thereby not only ensuring the dyeing effect, but also repeatedly utilizing the scouring and bleaching residual fluid, and being remarkable in water-saving and energy-saving effects.

Description

technical field [0001] The invention relates to a scouring, bleaching and paint dyeing process for pure cotton knitted fabrics, in particular to a method for performing scouring, bleaching and paint dyeing in the same treatment bath, and belongs to the technical field of textile printing and dyeing. Background technique [0002] There are a lot of impurities on the pure cotton knitted fabric, such as hemicellulose, pectin, wax, cotton seed hulls, natural pigments, etc., which make the fabric yellow in color and poor in water absorption, affecting its various properties. Therefore, it is necessary to carry out scouring and bleaching treatment for the purpose of removing natural impurities, so that the fabric can obtain good water absorption and clean appearance, so as to facilitate subsequent dyeing and other processing. Usually, in order to save energy and improve production efficiency, the scouring and bleaching of knitted fabrics are combined into one process, referred to ...
